i if E,

titane To all 107mm 'it may concern.' Be it known that l, HENRY BnLLoN, `a citizen of the United States, and a resident of Chicago, in the county of Cook and State of n Illinois, have invented certain newand use*` ful ln'iproyements in Eye Chaplets, of which the following is a specification.

This invention relates to impro'Vf-iments in chaplets and more ]')articularly to chaplets,

l@ so named because it is adapted for a particu- 5 lar use in foundry practice, na inely, informing` an eye orhole in n. casting. .A familiar illustration of the use of an eye chaplet is in the casting of stove or furnace doors, in

l5 which holes are provided for the purpose of hinging the door, or in Jthe `castingof sash weights in which an eye is proyided at one end.r y i.

It is characteristic of all chaplets that they 20 assume a Imultitude of shapes and forms depending on thecharacter of the casting, and so in the case of eye ehaplets they vary lcon-p siderablyy in their design and formation, althoughthey allf are characterizedby a com-` which produces inthe finished4 casting the desired eyeor hole. y Y. p

lfleretofore the common practice in the manufacture of eye ehaplets has been the V0 inakingand assembling` of at least two, and

sometimes. more, separate parts, which are stamped out of sheet metal in separate oper-` ations. This hasfbeenlargely dueto the tubular portion which must be first stamped out in the blank andthen shaped into cylindrie form" and the ends inserted through holes in the body portion of the cluiplet and finally crimped down toforin a secure joint.

The objectof the present invention is to i i EYE GHAPLET.

thaty other formsof eye chaplets may be' manufactured in the same manner. In the accompanying drawings, Fig. l is a perspectiveview of the chapletV blankl as it appears after the stamping operation,

Fig'. 2 after the initial foi'min operation7 and Fig. 3 is a perspective View of the chaplet in its final form. i

lt is to be understood at the "outset that the blanks are stamped frein sheet metal by feeding the metal preferably in strips into a punch press `and between "specially de signed dies which stamp and punch the blanks, in a single stroke of the press; F 1 illustrates one of the chaplet blanks. the same comprising a body portion l having a length considerably `greater than its width `and provided with rounded ends. Adjacent is a perspective' `View of the blank each end of the body arevholes 2 2 which N are punched frointhe body in such a manner that short upstanding flanges QL-Q sur round the holes. In diameterthe holes arc substantially one-half the width yofthe bo( y member and are .locatedconcentrically with respect to the rounded ends thereof.l

At oppositeiendsv of t-he body l and `lo-l cated on oppositesidesthereo'hare two ree'I tangular, sections `or` pieces off-metal 3-3 which are connected with the body by means of short and relatively narrow neck portions 4--4- The location of these rectangular pieces may be incre accurately defined `intheir relatien `to thefholes 9 2. If an This relationship clear iosed Fips. il.

the bending' or forming of'tlie" piece' into semi-cylindric form and to a radius equalv to that of the adj acent punched hole 2, :and finally the bending of the now cylindric piece.

3 and neck portion 4 over upon theb'o'dy' portion and along the line of connection between the neck portion and" the body'l, The result of this bending and forming is clearly shown 'in 2f wherein the' seini-cylindric portions surround'the adjacent half'of v their respeetiye'holes 2 in"abutting relation and-projects' throughthe slot 7`formed at,

along their bas'e'edges with the fianges`2L surrounding said holes, and the neckportions flattened down upon the top surface of the body l. p j f It is also to be observed that there is pro,- vided along theouterr edge of 4each rectangular piece 3 a short project'i'ngtongue 6.l Furthermore thereis cuty or punchedrv in thebody member immediately adjacent the base of each flange 2zL a small rectangular slot 7, tliese slots 7 7, as Well as the tongues 6 6, being located symmetrically With respect to the imaginary minor axes, heretofore `referred to, in locating=the rectangular pieces 3 3. After the initial bending and forming operation as hereinbe'fore described, the

tongues 6 6 project upwardly from the free margins of the now semi-cylindric portions 3 3'.

The finaljforming` operation is that of bending the body member intermediate its ends insuch a manner that it assumes a U- shape with the punched holes 2 2 in axial alinement With each' other and the semicylindric lportions brought into registering relation With each other, so their vertical edges are broughtinto edgewise contact and together formV a complete cylindric orttubular member whichv surrounds 'and enL closes theflanges 2 2a and abut against the body" portion adjacent the base ofV said flanges. Further-incre in; the' final `formingr operating-las just described. 'the tongue "6 of each semi-cylindric portion registers with the opposite "end of-tliebody member, this notclr and' slot connectioii forming what is commonly!termed a toy-lock, by bending the projecting-portion of. eachtongue over upon theffouteit' surface :of the body member. l In: itsfinal formthechapletis seen-tofconsist of av [lrshaped bodv member and a'itubulai-'portiey 'transyersely between the parallel'eiid portions fof saidj bodyy member. Ini'practic the body Vmemberservesr vas ani'aiichorfforthe 'cliapletfthereb insuring v its prbpe'rlocatlon and anchoragewithm the tubular portion inthe blank consist mold. Furthermore the tubular portion, which is to form the eye in the finished casting, is filled With sand, which is remoied after the casting is taken from the flask or y molding frame.

In the' manufacture of chaplets of this character, on a "commercial scale and'by automatic machinery, the so-called gang die would be used, so that a number of blanks would be stamped in a single operation, the dies being so designed that the minimum amount of Waste would result from the stamping operation.' This fact would there fore dispose. ofvany apparent objection to the so-called one"piece'method ofmaking chaplets as herein described. So far as-'the finished article is concerned`,`its chiefafcl-` vantage over the so-called twov piece ohap'let,l

resides'in the fact that it may be made'enti'rely bymachinery, thus eliminating eX- pensive hand labor, that is required in assembling and crimping togetherthe several parts ofthe two piece chplet, heretofore 1 i,

manufactured. The chapletof the present inyention is particularly desirable from the standpoint lof strength and abiltiyto withi stan'd pressure, inasmuch as the tubular member prevents any displacement 0r warping ofy the; body portion, lbeing'` anchored lar poi-tions formed fromf'a blankin which the tubular portioii consists of la piece"intelV gral Withsaidbodypoi'tion,V` n i l A chapl'et comprising a Ibody portion and a tubular portion formed from afblank; in which" thetubular portion consists of a reetangulal' piece integrally connected with said body lportion through the medium' off'a narronnecl portion@V K j 5; A chaplet comprising' afU-"sliapedi-body portion and af tubulaii portionfeiitendifng transversely of lsaid U-sliaped'potiongf said tubular portion in the blan consistiiig of rectangular piece of metal iiitgial'niithsaid body'm'ember., j j l Y l' 6.
